With the rapid development of expressways in Hubei Province,which brings more and more problems and pre-construction of the many problems left over from the more prominent in the conservation of these problems in the Highway Slope reinforcement was particularly notable, unique to the region in Hubei geological conditions, the slope of governance there are various problems and difficulties.This article is for Beijing-Macao Expressway in Hubei Province in K1050+290 cracks at the slope and the emergence of pure rock fall and other issues, pre-site survey through its unique access to hydrogeology, geomorphology, topography, lithology and structure and the information such as items on the basis of mechanical parameters, and conduct on-site measurements and observations of the high slope before the break Reinforcement body surface and break some of the characteristics shown, for the disease and the requirements of owners, after a number of options put forward than the election protection of a more appropriate project design. The program is designed primarily to carry out the following ideas, and to Beijing, Hong Kong and Macao at the highway cross-sectional analysis of K1050+225, in the grasp of the main factors for this slope changes and occurrence of damage to the mechanism of lines and other conditions, the use of engineering analysis Software management is to determine the slope of the potential sliding surface, analysis of slope stability factor before treatment to determine the reinforcement of this slope, the main supporting structure of gravity retaining wall and anchor. After the gravity retaining wall design should be checking the gravity retaining wall safety factor to ensure the effectiveness of the reasonable time retaining wall; in the Anchorage area, by reason of the bolt is software design, the final calculation Anchorage slope after the driving forces, find the slope stability factor to reach the department is checking the stability of the slope to reach the engineering design requirements and trade-offs are more economical bolt and so on. This slope to gravity retaining wall and bolt the integrated use of the same time, further optimization of the drainage system to reduce the future impact of water on the second slope, to ensure the long-term stability of the slope. In the end the finite element method through the block structure of these two theoretical integrated use of its checking, verification of high slope of the arrival had been strengthened after the treatment requirements of the engineering safety and reliability to ensure the feasibility and reasonable sex. Finally, before and after Treatment in the slope, the slope should be observed to ensure continued. To prevent the actual situation may be different from expectations, the need for dynamic design method of the use of information, the extent of damage to the slope, moving direction and speed, and groundwater monitoring. If there are special circumstances, treatment measures should be adjusted.Instance through the analysis of this project and research works on the slope have a more in-depth understanding and knowledge, and further understanding of the theoretical analysis and calculation of slope and be able to put these theories into practice project, undertaken in the project in the future according to project-specific conditions and characteristics of rapid reinforcement to take an effective governance program.
